YSI 9600 - Manual (Page 38)

If the test was passed, simply click “OK” and then click the Next button to proceed to the final set-up
screen.
If the display indicates that there was a failure in the predeployment systems test, note the nature of the
failure mechanism as shown above:
1. The error message on the left indicates that the absorbance readings from the sample and standard
(which are identical in the Predeployment Check) differ by more than the standard tolerance.
2. The error message on the right indicates that the absorbance readings from the two runs differ by more
than the standard tolerance.
3. The error message at the bottom indicates that the absorbance readings of either the standard or the
sample (or both) are too low.
Next see Section 10, Troubleshooting, for help in overcoming the problem and repeat the Predeployment
Check by clicking the “Yes” button on any of the error codes to return to the first screen of the Deployment
Wizard as shown below.
If the error messages continue to be observed, click the “No” button in the error window to show the
following diagnostic screen.
